CONCERNING...SEVERE THUNDERSTORM WATCH 6...

VALID 260054Z - 260200Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 6 CONTINUES.

SUMMARY...A LINE OF THUNDERSTORMS FROM CENTRAL THROUGH NORTHEAST
OKLAHOMA INTO NORTHERN ARKANSAS WILL CONTINUE TO TRACK SOUTHEAST
DURING THE EVENING. A THREAT FOR SEVERE HAIL WILL CONTINUE THE NEXT
FEW HOURS...BUT THE TORNADO THREAT APPEARS TO HAVE DIMINISHED.

DISCUSSION...RADAR TRENDS OVER THE LAST HOUR OR SO CONTINUE TO SHOW
THUNDERSTORMS CONGEALING INTO A SOUTHEASTWARD-MOVING LINE. MOST OF
THE LINE APPEARS TO BE WELL BEHIND THE SURGING SURFACE COLD FRONT.
IN CONCERT WITH INCREASING SBCINH...THESE STORMS WILL BECOME MORE
ELEVATED AND GENERALLY WEAKEN WITH TIME AS DIURNAL COOLING CONTINUES
AND UPPER FORCING FOR ASCENT SHIFTS NORTHEASTWARD.
HOWEVER...MIDLEVEL LAPSE RATES CONTINUE TO BE STEEP...FROM 7.5 TO
8.5 DEGREES C PER KM AS INDICATED IN 00Z OUN...LZK AND FWD RAOBS.
THIS WILL ALLOW FOR SOME HAIL THREAT TO CONTINUE FOR ANOTHER 2-3
HOURS. FURTHERMORE...THE TORNADO THREAT HAS GREATLY DIMINISHED AS
THE SURFACE BOUNDARY HAS SURGED AHEAD OF THE STORMS.
